Abstract
Cell coordinates available in the radio network is used to determine an area where the mobile radio is located and does not rely upon mobile radio measurements. Such cell coordinates for cells currently associated with the mobile radio are used by the radio network to determine a location of the mobile radio. Those current cells may include cells that are candidates for supporting a communication with the mobile radio, an active set of cells, cells that are currently supporting communication with the mobile radio, or some other set of cells geographically associated with the mobile radio.

12. A method for determining a location of a mobile radio comprising:
-
obtaining previously determined coordinates of plural cells in a set of cells associated with the mobile radio, where each coordinate may be defined with a horizontal coordinate and a vertical coordinate;
analyzing a first group of lowest horizontal coordinates for the set of cells and selecting a highest coordinate from the first group;
analyzing a second group of highest horizontal coordinates for the set of cells and selecting a lowest coordinate from the second group;
analyzing a third group of lowest vertical coordinates for the set of cells and selecting a highest coordinate from the third group;
analyzing a fourth group of highest vertical coordinates for the set of cells and selecting a lowest coordinate from the fourth group;
determining a location of the mobile radio using the selected coordinates from some or all of the first, second, third, and fourth groups. - View Dependent Claims (13, 14, 15, 16, 17)
